WHEEL CLAMP.

Application filed October 3, 1921.

To (ML/1 7mm it may (JOHGGTIL! Be it known that 1 BLAGOYE D. Mrr- SAREFF, a citizen of the United States, residing at Wolf Point, in the county of Roosevelt and State of Montana, have invented certain new and useful Improvements in ll heel. Clamps, of which the following is a specification.

This invention relates to wheel clamps, for use in connection with the wheels of railway cars.

An object of the invention is to provide means whereby the wheels of a railway car may be clamped to the rail, so that the body of the car can be raised from the truck, when it is desired to re-brass the axle.

Another object of the invention is to pro vide such a clamp which is extremely simple in construction, strong, durable and highly convenient in use.

Other important objects and advantages of the invention will be apparent during the course of the following description.

In the drawings, wherein like numerals are employed to designate like parts t iroughout,

Figure 1, is a side elevation of one form of clamp, as applied to the rail. and wheel,

Figure 2, is a perspective view thereof,

Figure 3, is a view similar to Figure 1, but illustrating a slightly diiierent form of the invention, and,

Figure 4%, is a side elevation of the form of clamp shown in Figure 3, with parts broken away for the purpose of illustration.

Referring to the drawings in detail, the numeral 5 designates the rail tie, and 6 the rail. 7 indicates a car wheel of the usual and well known construction, having a journal box 8.

Referring to Figures 1 and 2. the numeral 3) 1lesignates a clamp as a whole, having a shank 10, provided with a prong or pointed end 11 and a depending arm 12 at one extremity. At its other end, the shank is divided to form arms 13 and 1 1, these arms having teeth 15 and 16 formed thereon, as shown. The arm 12 is provided with teeth 17 upon its outer face. The numeral 18 indicates a jack block, having a jack 19 mounted thereon. It is to be understood that the jack may be of any well known Serial No. 504,916.

make or form. If desired, a chain 20 may be employed to permanently attach the clamp to the jack block, but it will be obvious that this is not necessary to the operation of the invention.

In the use of the invention just described, when it is desired to put new brass around the axle of a railway car, the clamp is first brought into use, the arms 13 and 14 brought into engagement with the inner surface oi the flange of the wheel and the under side of the ball of the rail. The block is then moved into engagement with the prong 11, which. bites into the side of said block. The jack is then placed upon the block and operated until it firmly presses against the under side of the journal box and the top of the block. It will be obvious that such action will prevent slipping of the block and consequently preventing the clamp from becoming disengaged from the rail and wheel flange. If the rail is of such height that the prong 11 cannot be conveniently used, the arm 12 will then be placed against the side of the block, with the prong 11 laying on top. When the clamp and associated elements have been placed, the body of the car may then be raised, without danger of also raising the wheels from the track.

In the form of the invention shown in Figures 3 and a, a shank 21 is provided with a prong 22 and arm 23, corresponding to the prong 11 and arm 12 before described. The shank 21 is also provided with an arm 24 corresponding to the arm 14. An arm or shank 25 is formed upon the shank 21 at a right angle, and is provided with teeth 26. An arm 27 adapted to co-act with the arm 24- is movable upon the arm 25. As shown in Figure 1 this-arm 27 is provided with an opening 28 therethrough. for the reception of the arm 25. The walls of this opening are cut diagonally, and one side wall is provided with teeth 29 adapted to engage with the teeth 26. A spring 30 secured to the arm 27 at 31 is of such configuration as to hear at all times against the side of the arm 25. It will be obvious that the action of the spring will at all times force the teeth 26 and 29 into engagement. Pressing the outer end of the arm 27 down will disengage the teeth .25 and 29 th reby allow an ad justment of the arm 27 with respect to the arm 25. The purpose of the adjustment is to take care of varying sizes of car wheels and rails, such as the ear wheels on a freight car, and those on a passenger car.

The operation of this form of: the invention will be apparent, the same block and jack being used as before described. hen it is desired to place the clamp on the wheel and rail, it is first necessary to engage the arm 2st with the underside of the rail ball and then bringthe arm 27 down until it engages the inner surface of the flange of the wheel. The block .is then positioned as before and the jack adjusted thereon.

It will be apparent from the l oregiing description that'the device of the present invention is of simple and economical construction and that it may be easily and quickly put in place and will securely hold the wheel upon the rail while the car body is being raised from the truck.

It is to be understood that the form ol the invention herewith shown and described is to be taken as the preferred ones thereof, but it is also to be understood that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having described my invention what I claim is 1. In a device 01 the character described the combination with a clamp having a forked inner end adapted to embrace the ball of a rail and. the iange of a car wheel and having a longitudinally projecting prong at its outer end, of a wooden jack block adapted to be penetrated by said prong and a jack adapted to rest upon said block and hold said block in place when said jack is in action.

2. A device oi the character described comprisiim in combination a clamp provided with forked inner end adapted to embrave the ball of a rail and the flange of a wheel and. provided at its outer end with a longitudinally extending prong and a downwardly projecting arm having a toothed outer face, of a wooden jack block .u'lapted to be engaged either by said prong or by the teeth of the arm and a jack adapted to rest upon said block and to exert a thrust thereon when the jack is in action.

In testimony whereof I alhx my signature.
